    I do not believe any pit bike motor will be "bolt in". Just about every pit bike engine I've seen is based on the ATC70 variant of engine. The 125m uses a ATC90 style engine. There are lots of old bikes that used the ATC90 style engine but very few new bikes.

    I'm sure with a little bit of work you could make your pit bike engine fit the 125m. I know several people have done it before you.
    And that's the rest of the story. ~ Paul Harvey
